@Padma Mody My problem with your first post is that it seemed disingenuous.
Your gave the impression that she was being forced out by section 8 due to an irreparable HVAC system. That if it could have been fixed, she'd have been able to stay. That's why you got so many responses regarding it's repair.
Perhaps it's just in the way you wrote it but if you wanted her out so you could renovate, you should have just said so in your first post. I see nothing wrong with that, as long as you gave her proper notice, etc.
I also have no issue with you going there to see if she had vacated. I would have done the same thing.
@Account Closed because this is a "landlord site" are we to always side with the landlord? I agree that discourse should always be civil but I think this is a great site because we can get honest peer feedback regarding our decisions and practices as landlords. I don't want people here to ever automatically side with me out of a sense of filial duty. Don't you agree?
